Abstract
The invention concerns a unit (1000) for controlling transmission of power to a thermal conditioning device (100) e.g. for coffee machine, comprising a controller (2) with a start-up profile for starting-up said device (100) from a temperature of inactivity (TI) to an operative temperature for bringing to a target temperature (TT) a fluid circulating through said device (100) at start-up end, said controller (2) being arranged to allow circulation of fluid through said device (100) at start-up end and to compare the determined temperature (SOT) of fluid circulated at start-up end to the target temperature (TT) and derive a temperature difference therefrom. It is characterized in that the start-up profile has at least one parameter and in that said controller (2) has a self-learning mode for adjusting said parameter as a function of said temperature difference and to store the adjusted parameter for a subsequent starting-up of said device (100). The invention concerns in particular a method for optimized heating up of a coffee machine (104).
